        # Clear out cached entries - use low level expire_fragment, even though
        # we are clearing results from caches_action, for several reasons:
        # * We can't use expire_action here, as doesn't  seem to be
        # compatible with the :only_path we used in the caches_action
        # call. 
        # * expire_fragment lets us use a regular expression which is
        # simpler than having to get all the parameters right for the
        # path, and calling for HTML version vs. raw attachment version.
        # * Regular expression means we cope properly with filenames
        # changed by censor rules, which change the URL.
        # * It's also possible to load a file with any name by changing
        # the URL, the regular expression makes sure the cache is
        # cleared even if someone did that.
